Setting Up the Network How to Set Up the Network DETAILED STEPS Step 1 Command or Action ip dhcp pool pool-name Step 2 Example: Router(config)# ip dhcp pool mypool network ip-address [mask | prefix-length] Step 3 Example: Router(config-dhcp)# network 10.0.0.0 255.255.0.0 option 150 ip ip-address Step 4 Example: Router(config-dhcp)# option 150 ip 10.0.22.1 default-router ip-address Example: Router(config-dhcp)# default-router 10.0.0.1 Step 5 exit Purpose Creates a name for the DHCP server address pool and enters DHCP pool configuration mode. Specifies the IP address of the DHCP address pool and the optional mask or number of bits in the address prefix, preceded by a forward slash. Specifies the TFTP server address from which the Cisco IP phone downloads the image configuration file. This needs to be the IP address of Cisco Unified CM. Specifies the router to which the  Cisco Unified IP phones are connected directly. • This router should be the Cisco Unified SRST router because this is the default address that is used to obtain SRST service in the event of a WAN outage. As long as the Cisco IP phones have a connection to the Cisco Unified SRST router, the phones are able to get the required network details. Exits DHCP pool configuration mode. Example: Router(config-dhcp)# exit Defining a Separate DHCP IP Address Pool for Each Cisco Unified IP Phone This task creates a name for the DHCP server address pool and specifies IP addresses. This method requires you to make an entry for every Cisco Unified IP phone.
